+| 2026-04-29T04:38:45Z | claude-opus-4-7 | 26f978a2 | fifth merge wave + paired-edit + arithmetic fixes. PR #769 (third-merge-wave shard) squash-merged onto main — 11 PRs total this session arc. PR #770 lint failure caught and fixed: the `memory-index-integrity` workflow flagged that the verbatim-preservation memory file edit had no paired MEMORY.md update; fixed by appending the Amara-packet description to the existing MEMORY.md entry (rather than adding a duplicate-pointer entry, which would re-trigger `audit-memory-index-duplicates.sh`). PR #768 thread fixes: two arithmetic-inconsistency findings from Copilot (claimed "Six PRs merged" but listed 7; claimed "3 threads resolved" but narrated only 2) — both fixed in the shard text and threads resolved. PR #771 just opened, CI in flight. | [#769 merged](https://github.com/Lucent-Financial-Group/Zeta/pull/769), [#768](https://github.com/Lucent-Financial-Group/Zeta/pull/768) [#770](https://github.com/Lucent-Financial-Group/Zeta/pull/770) [#771](https://github.com/Lucent-Financial-Group/Zeta/pull/771) | Trajectory observation: two new-class findings hit this tick — paired-edit lint (memory file change without MEMORY.md update) and arithmetic-inconsistency (counts not matching enumerated lists). Both are mechanical, both responded to small commits, both are now recorded inline in this tick-history shard (the implicit "recurring-fix-class" reference here means the cumulative pattern visible across consecutive shard rows; no separate catalog file is tracked). The convergence pattern holds: each tick the set of recorded patterns grows slightly (covering more failure modes) but the per-finding fix cost drops as the patterns become familiar. Aaron's seven-step meta-loop is firing predictably across these. |
